PULLEY-MOUNTING.

- Specification of Letters Patent. Patented J 119 10, 1919,

Application filed September 21, 1918. Serial No. 255,071. I

To all whom it may concern:

Be it known that I, HERBERT G. BEEDE, a citizen of the United States,residing at Pawtucket, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Pulley-Mountings,of which the following is a specification.

This invention relates to certain new and useful improvements in pulleymountings, and pertains more particularly to a mounting used inconnection with a take-up pulley for spinning machines.

In spinning machines of certain classes or types, the band drives twospindles, one on either side of the machine, but more generally, theband drives four spindles, two on each side of the machine. Owing to thetwist necessary to divert the band, or alter the direction of itsmovement from a straight line, the take-up pulley must be set at acorresponding angle to permit free traction of the band. In some typesof machines the band must be diverted from a straight line, in adirection to the right, while in certain other machines the band must bediverted from a straight line in a direction to the left.

The present invention therefore aims to provide a pulley mounting whichenables the pulley to be set by a mere slight movement thereof, from aright to a left position, or vice versa. In brief, the pulley is carriedby a, mounting which is set by moving same to assume an inclineddirection to the right or left, and is held in such position by a screwor equivalent, so that the two adjustments can be easily and quicklyeffected by merely altering the position of the mounting.

In the drawings- Figure 1 is a side elevation, showing parts in sectionand the invention applied to a spinning machine, the latter shown infragment and partly in section.

Fig. 2 is a longitudinal sectional view of the bearing whichforms a partof the pulley mounting.

Fig. 3 is a view similar to Fig. 2, showing the bearing set to aposition to the left.

Fig. 4 is a view similar to Fig. 2, but with the shaft omitted, and

Fig. 5 is a detail perspective view of the bearing looking into the endthereof.

In proceeding in accordance with the present invention, a bearing 1 isemployed whichhas a cut-out 2 leading from its center radially throughthe periphery of the bearing. The bearing is formed at about its centerwith two oppositely inclined grooves 3 and 1 which intersect centrallyof their lengths as depicted in Fig. 4, the grooves being formed so thatone is located to the rear of the other.

A fixture or bracket 5 is carried by the bearing 1 and has anupstandingarm 6 to which the pulley 7 is suitably journaled, the bracket furtherhaving a depending counterweighted part 8, and a curved slot 9. A setscrew 10 extends through the slot 9 and through a hole 11, providedtherefor in the bearing 1, having threaded engagement with the wallsdefining hole 11, and engaging a shaft 12.

The shaft 12 is squared and the grooves 3 and 1 are shaped to conformthereto. The bearing 1 has its periphery engaged by the wall of a curvedor segmented opening formed in the fixture 6, so' that the fixture canrotate about the bearing to a partial extent governed by the limit ofthe length of the slot 9 of the fixture engaging the set screw 10. Thusthe in and out or swinging movement of the pulley 7 borne by the fixture6 is limited or defined.

In operation, it will be apparent that to shift from a right to a lefthand set of the take-up pulley 7, it is merely necessary to loosen setscrew 10 so as to allow the shaft 12 to be engaged in the correspondinggroove 3 or 4 as the set may require, whereupon the set screw is againtightened so as to firmly connect the bearing to the shaft, the bearingbeing moved from the position of Fig. 2, to that shown in Fig. 3, orvice versa, depending upon the required set of the takeup pulley as isbelieved manifest.

The belt shown at B it will be understood passes around both spindlesand the pulley as well as the drive cylinder G and has a, twist asshown. The counterweight serves to overbalance the tension pulley 7,thereby maintaining a constant tension upon the belt B.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is 1. In a pulley mounting, in combination witha shaft, a bearing mounted on the shaft and having a pair of crossedinclined shaft receiving grooves located at about its center and alsohaving a radial cut-out leading into the center, a fixture rotatablymounted over the bearing and having a radial slot, 3. pulley journaledon the fixture, and a set screw extending through the slot andbearing'and' ing on the shaft having a pair of crossed in-'- clinedgrooves therewithin with a cut-out leading radially through the bearing,said grooves bein formed'to receive the shaft so as to allow the bearingto be tilted to either the right or left, and a pulley carrying fixturecarried by the bearing.

3. In a pulley mounting, a shaft, a bearing'on'the shaft having groovestherein to receive the shaft SOELS' to allow the bearing to be tiltedwith respect to the shaft, and a 15 pulleyrotatably carried by thebearing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HERBERT a BEEDE.
